Solution:

Here is the code.

1. public class PatternBrainly {
2. public static void main(String[] args) {
3. String s="EDUCARE";
4. int n=s.length();
5. for(int i=1;i<=n;i++)
6. {
7. for(int j=0;j<n-i;j++)
8. System.out.print(" ");
9. System.out.println(s.substring(0, i));
10. }
11. }
12. }

Explanation:

Before we start, you must know the syntax of substring function.

Syntax:- <string>.substring(int startIndex, int endIndex)

Let us divide the pattern into two parts - first part for spaces and second part for the spaces.

• For the first row, you can see that total number of spaces is 6, then for the next row, it is 5 and so on. So, we will print spaces n - i times (n = 7, i=1,2,...)
• Now, we will use the substring feature. We will display the substring from index 0 to i (where i = 1,2,3,..)
• In this way, the pattern is solved.

Output is attached for verification.
